API Testing with JavaScript and Cypress 10

Common HTTP methods

How to execute web requests

Basic and advanced API automation

Setup, Run Test and API Implementation


  • Basic understanding of JavaScript


API testing with JavaScript is an important part of the software development process. It ensures that the application is working as expected and is able to facilitate communication between different components.

By running tests on the API, developers can ensure that the functionality of the application is intact and that any changes made to the system don’t affect the overall performance of the application. JavaScript makes it easy to write and execute tests, enabling developers to quickly and easily verify that their software is working correctly.

With the right testing tools, developers can ensure that the APIs they are working with are reliable and secure. This is essential for ensuring that the application is able to provide the desired results.

In this new tutorial, you will learn how to implement automated API testing with Cypress 10.

What our students are saying?

“I appreciate the time the instructor put on this course as well as the opportunity to get familiar with TestProject free of charge. Well explained, however, if you are using Windows and you are new in Automation Testing, you might find it a bit challenging with adding the SDK Token in your system environment since the instruction used MAC which is completely a different way with windows. Other than that… I appreciate a lot this free course …. thank you so much”

I like the fundamental approach used by the author. Will see:) To prepare for such a course – it’s a really hard and big job. Respect and thank you.” – Serhii Kovalenko

Wonderful content and things explained in a nutshell. Overwhelmed by Author’s dedication to putting things in such a way that any novice or manual tester can follow and understand and definitely be on-boarded as a Selenium Automation Engineer the next day at work. Thanks a million times for creating these courses! One Stop for Automation.” – Rupashree Geethaaviji Ananthakrishna

“I am familiar with Nikolay from a course I saw on TestAutomation and have the highest regard for him. Glad to see him on Udemy.” – Annamalai Viswanathan
